Why does the glass stem in a clinical thermometer act as a magnifying glass?
The glass stem in a clinical thermometer acts as a magnifying glass because it is made of a transparent material that can refract and focus light. When you hold the stem over a scale, it magnifies the divisions on the scale, making it easier to read the temperature.
Why the stem of a clinical thermometer is thick?
The stem of a clinical thermometer is thick to allow for better heat conduction between the body and the thermometer bulb, ensuring an accurate temperature reading. A thicker stem also provides durability and strength to withstand repeated use.
Why is the glass stem on a clinical thermometer designed to act like a magnifying glass?
The stem of the thermometer is not perfectly round for two reasons. One so it will not roll off and fall, and two, the flat area acts as a magnifying glass to make the hollow shaft in the stem appear larger.
Why is the stem of a thermometer designed like a magnifying glass?
So you can read it more easily.
Why does a stem in clinical thermometer have a small cross section area?
The small cross section of a clinical thermometer is there to reduce the amount needed of the toxic mercury to as little as possible. Mercury is less used nowadays, as breakages were likely due to the violent shaking needed to 'reset' the thermometer.
Why is the stem of a thermometer designed as a magnifying glass?
The stem of a thermometer is not designed as a magnifying glass. The stem of a thermometer is typically narrow to allow for more accurate temperature readings, as it reduces the amount of time it takes for the reading to stabilize. The magnifying glass may be used for easier reading of the temperature scale on the thermometer.
What is immersion thermometer?
A total immersion thermometer is one that has been calibrated to read correctly when the entire thermometer is submerged in a homogeneously temperated liquid/medium.
What Dial stem thermometer should range between?
A dial stem thermometer typically ranges between -50°F to 500°F (-45°C to 260°C).
Why does the mercury fall or rise in a clinical thermometer when it is taken out of the mouth?
A clinical thermometer measures the max temp of the human body due to the expansion of the mercury in the bulb, which flows past a kink in the column and rises in the graduated stem, to read the highest body-temp. Once it is removed from the body, the mercury stays at that level, and does not fall because it cannot flow back into the bulb -- the kink prevents the back flow. It has to be shaken vigorously, as you know, for us to get the mercury back; then it is ready to take the temp again.. Also, the temp cannot rise further on its own from the max reading because the mercury does not expand the moment the thermometer is taken out of the body. Incidentally, temp can be measured under the armpits and in the rectum also.
Why clinical thermometer often have oval stem in cross section?
Two advantage and two disadvantage of using alcohol and Mercury for thermome Two advantage and two disadvantage of using alcohol and Mercury for thermometer
Explain why a thermometer thick walls on its stem?
Thick walls on the stem of a thermometer provide insulation and reduce heat transfer from the environment, resulting in more accurate temperature readings. This helps to prevent external factors, such as air temperature fluctuations, from affecting the measurement inside the thermometer.
A dial stem thermometer should range between?
A dial stem thermometer typically ranges between -18°C to 260°C (-1°F to 500°F). It is important to check the specific range of the thermometer you are using to ensure accurate readings within its limits.
